2 DVC6200 Digital Valve Controller Instruction Manual Supplement Introduction Product Overview The FIELDVUE DVC6200 digital valve controller is designed to control the pneumatic actuator of a process control valve. It receives a current signal from a host and uses instrument air supply to create a metered pressure output signal to the pneumatic actuator. Movement of the actuator as it positions the process control valve is measured by the DVC6200 travel sensor as its primary feedback. The name plate is located on the bottom side of the DVC6200 master module assembly and indicates the model name, individual product serial number, and any applicable third party approvals. Purpose of this document This specification is designed to be a technical reference for HART capable host application developers, system integrators and knowledgeable end-users. It also provides functional specifications (e.g., commands, enumerations and performance requirements) used during field device development, maintenance and testing. This document assumes the reader is familiar with HART Protocol requirements and terminology. Additional product information is available in DVC6200 product literature, available from Emerson Process Management.

4 DVC6200 Digital Valve Controller Instruction Manual Supplement Product Interfaces Control Valve Interface The DVC6200 digital valve controller is mechanically attached to the valve s actuator by means of a mounting bracket. The control valve's position is conveyed to the travel sensor of the DVC6200 digital valve controller by means of the feedback bracket and magnet assembly attached to the actuator s stem. ACTUATOR FEEDBACK BRACKET AND MAGNET ASSEMBLY MOUNTING BRACKET DVC6200 DIGITAL VALVE CONTROLLER X Pneumatic tubing connected to the DVC6200 brings instrument supply air to the DVC6200 and takes controlled output air from the DVC6200 to the actuator. Pressure sensors in the DVC6200 measure these pressure signals and present them as device variables Host interface The input to the DVC6200 can either be two wire 4 to 20 ma current loop (in point to point mode) or 24 VDC (in multi drop mode). This input is connected in the DVC6200 s terminal box on two terminals marked LOOP + and LOOP. Refer to the DVC6200 Series quick start guide for connection details. Pushbutton Calibration A pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the travel of the instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is disabled by default. 4

5 Instruction Manual Supplement DVC6200 Digital Valve Controller Internal Jumpers And Switches (Optional) The input to the DVC6200 is determined by the Pt Pt/Multi Drop switch on the printed wiring board. The DVC6200 also has a pair of optional Output terminals that can either function as a position transmitter or a discrete switch. Electrical configuration of the output circuit requires the proper setting of a DIP switch on the DVC6200 s printed wiring board. Additionally, the functional operation of the output circuit must be configured with the user interface. Refer to the DVC6200 instruction manual for additional details on the settings of the selection switches. WITH OPTIONAL I/O PACKAGE DIP SWITCH FOR TRANSMITTER/SWITCH SELECTION X0430 OUTPUT+ OUTPUT- PT-PT/ MULTI-DROP SELECTION X0432 WITHOUT I/O PACKAGE PT-PT/ MULTI-DROP SELECTION X0427 X0431 Write Protection There are two Write Protection states for the DVC6200: Not Protected or Protected. Protected prevents configuration and calibration changes to the instrument. The default setting is Not Protected. Protection is controlled under software control. Write Protection can be enabled remotely. However, to disable Write Protection to Not Protected, you must have physical access to the instrument. The procedure will require you to press a button inside the terminal box when directed by the software as a security measure. 5

10 DVC6200 Digital Valve Controller Instruction Manual Supplement Command 15: Read Primary Variable Output Information This command returns the upper/lower range values for the primary variable which is defined to be the loop current signal. These are the loop current values for the ends of physical travel, and are used to derive set point from the loop current. It reports the range supplied in Command 35. For example, the lower range, for an increase to open valve, will be the current which will produce a 0% set point. However, for an increase to close valve, the lower range will be the loop current for a 100% set point. The range values can be changed via Command 35. The DVC6200 assumes 0% = 4mA and 100% = 20mA.

18 DVC6200 Digital Valve Controller Instruction Manual Supplement Command 35: Write Primary Variable Range Values In the DVC6200, the Primary Variable is defined to be the Analog Input (loop current). This command is used to write the ranging values reported in Command 15. It controls how the DVC6200 interprets the loop current when creating the Travel Target. The upper range must be greater than the lower range. This command does units conversion, accepting range values in milliamps or percent. If the primary variable is not configured to use the same units as supplied in this command, the supplied ranges will be converted to PV units before being applied. Range values are validated against those reported in Command 14 to assure that they are within the allowable range and are separated by a minimum span. If the range values are in percent, then they are assumed to be percent of 4 20 ma. For example, to range an increase to open unit from 8 ma to 16 ma, but using percent range numbers, specify lower_range = 25% and upper_range = 75%. This ranging is done in conjunction with the zero power condition. For an Increase to Open valve, the lower range is the 0% setpoint level (valve plug in the valve seat), while the upper range is the 100% setpoint level. An Increase to Close valve is exactly opposite. This command will be accepted when the DVC6200 s Instrument Mode is In Service but will be rejected if Write Protection is in effect.

19 Instruction Manual Supplement DVC6200 Digital Valve Controller Command 42: Perform Master Reset This reset command has two options. If no data bytes are supplied, respond immediately and then perform a warm reset. This is not equivalent to power up in that restart modes and default IVP are not adopted and the real time clock is not reset. All other data is read from nonvolatile memory and put into effect. The second option is hard reset. This requires two data bytes set as described below. If this form is received, the unit will save modes and counters, then execute a hard reset by exercising the watchdog timer. The next response will have the cold_start bit set. A soft reset command will be honored while the DVC6200 Instrument Mode is in the In Service condition. A hard reset command requires the DVC6200 Instrument Mode be in the Out of Service condition. Request Data bytes Data Bytes Command specific Codes Byte Format Description 0 1 Uint16 None Code Class Description 16 Error Access Restricted [Optional] If hex 0x6969 is supplied as request data bytes, a hard reset is performed. Otherwise a soft reset is performed. Command 44: Change Primary Variable Units Code This command is issued to change the units of the Primary Variable, which is defined in the DVC6200 as the Analog Input (loop current). The choices for units are Percent (code 57) or Milliamps (code 39). This command will cause variable 0 (loop current), and the response to Command 14, to be reported in the new units. In addition to changing the units code, execution of this command will also change the DVC6200 s Analog Input Upper and Lower Range values to reflect the new units. (For example: When the DVC6200 s Analog Input is configured as 4 20 ma and Command 44 with request Data Byte 57 is executed, the DVC6200 s Analog Input units and range values will change to 0 100%. Likewise, when the DVC6200 s Analog Input is configured as 0 100% and Command 44 with request Data Byte 39 is executed, the DVC6200 s Analog Input units and range values will change to 4 20 ma ). This command will be accepted when the DVC6200's Instrument Mode is In Service, but will be rejected if Write Protection is in effect.

24 DVC6200 Digital Valve Controller Instruction Manual Supplement Annex B DVC6200 Parameters as part of a Rosemount 1410 / 1420 WirelessHART Gateway A FIELDVUE DVC6200 can join a wireless network through the addition of a Rosemount 775 THUM WirelessHART adapter. The wireless adapter acts both as a HART modem for communications coming to the DVC6200 from application software and as an independent master issuing commands periodically to the wired device pertaining to it s status. This independently gathered status information is relayed back to the Rosemount 1410 or 1420 Wireless Gateway and is made available to the user either through viewing the HTML interface or via mapping as Published Data parameters via the Gateway s MODBUS or OPC outputs. For HART 5 devices the PV, SV, TV, and QV variables can be mapped. For HART 7 devices up to 8 variables can be mapped. Configure the THUM as follows: Navigate to Configure > Manual Setup Under the Wired Device tab select Configure HART Polling Wired Device tab FOR PRIMARY DEVICE INFORMATION: HART 5 - select PV, SV, TV, and QV HART 7 - select Process Variables with Variable Status Choose Variables 0, 1, 2, 4, 6, 8, 9, and 10 Select Yes if changes are required FOR SECONDARY DEVICE INFORMATION: Both HART 5 and HART 7 - select Device Status 24

25 Instruction Manual Supplement DVC6200 Digital Valve Controller The FIELDVUE instrument is defined on the Gateway by Tag (read from the device s Message field). For each Tag, the Gateway provides updated values for: Variables Additional Status Published Data HART 5 HART 7 25

26 DVC6200 Digital Valve Controller Instruction Manual Supplement Published Data, used for the Gateway s OPC and Modbus outputs, falls into the following categories: Field Device Identification Values: Values that define the identity of the DVC6200. These include: MANUFACTURER (for Fisher Controls the value is 19 ) DEVICE_TYPE (for a DVC6200 the value is 9 ) DEVICE_REVISION HARDWARE_REVISION SOFTWARE_REVISION DEVICE_ID UNIVERSAL_REVISION (HART version) REQUEST_PREAMBLES RESPONSE_PREAMBLES Variable information: The Gateway receives updates concerning the DVC6200 s configured device variables. The information for any given device variable is displayed by: 1. Dynamic Variable indicator ( PV, SV, etc.) 2. The Device Variable ID number assigned to that Dynamic Variable 3. By the Device Variable Name (only if the Gateway has version 4.4 firmware or later) Dynamic Variable Device Variable ID Device Variable Name(s) Analog Input PV 0* ANALOG_INPUT Internal Temperature 1 INTERNAL_TEMPERATURE Pressure TV 2* PRESSURE_PORT_A Travel 3 TRAVEL Drive Signal 4 DRIVE_SIGNAL Pressure 5 PRESSURE_PORT_B Travel Setpoint 6 TRAVEL_SETPOINT Pressure 7 DIFFERENTIAL PRESSURE Pressure 8 SUPPLY_PRESSURE Implied Valve Position SV 9* IMPLIED_VALVE_POSITION Travel QV 10* PRIMARY_FEEDBACK Milliamp Current 245 CURRENT *Default Value indicated 26

27 Instruction Manual Supplement DVC6200 Digital Valve Controller Any of these choices [Dynamic Variable, Device Variable ID, or Device Variable Name(s)] can be substituted for the # sign in the Variable Identifier fields below. Variable Identifier Comments / Explanation # See any of the variable identifiers in the table immediately above. #_CLASS Always 0. #_CODE The Device Variable ID number in the table immediately above. #_HEALTHY A true or false indication of the health of the sensor providing this value. #_STATUS #_UNITS Decimal Variable Units code number from the Units Codes table on page 7. Device Status: The eight standard status conditions (present in ANY HART field device) are all represented by a Boolean true or false state. These eight conditions, discussed on page 7, are: DEVICE_MALFUNCTION CONFIGURATION_CHANGED COLD_START MORE_STATUS_AVAILABLE LOOP_CURRENT_FIXED LOOP_CURRENT_SATURATED NONPRIMARY_VALUE_OUT_OF_LIMITS PRIMARY_VALUE_OUT_OF_LIMITS Detailed Device Alerts: The Alert Groupings are: ADDITIONAL_STATUS_0 ADDITIONAL_STATUS_1 ADDITIONAL_STATUS_2 ADDITIONAL_STATUS_3 ADDITIONAL_STATUS_4 ADDITIONAL_STATUS_5 ADDITIONAL_STATUS_6* ADDITIONAL_STATUS_7* ADDITIONAL_STATUS_8* 27

28 DVC6200 Digital Valve Controller Instruction Manual Supplement Each of these status bytes represent eight individual bits with values that range from 00 to 255. To determine which of the eight bits are active requires converting a decimal value to its binary equivalent value. Refer to Command 48 on page 12 for details on the individual alert bits inside of each Additional Status Byte. Note Gateways with firmware version 4.4 define the alerts of DVC6200 hardware 2 devices.
